Three percent of all the electronic components in the world become obsolete every month. When you imagine all the shit coming out of China, it's pretty staggering. The problem is actually worse for the military, which spends about $10 billion a year on keeping up obsolete electronics parts. Ironically it's because they've switched to using off-the-shelf consumer electronics for 90 percent of their components—with a much shorter service life, four years at best—rather than "military-spec" gear, which was designed to hang around for a decade or more.

IEEE Spectrum lists a couple of egregious examples: The B-2 Spirit, one of Jesus' favorite planes, started flying in 1989, and by 1996, lots of its electronic components were obsolete. And in the Navy's new sonar system, 70 percent of the parts were obsolete when they started installing it.

Finding the parts isn't just difficult, it's expensive as hell, so the cost of maintaining obsolete but very necessary wares basically keeps you from upgrading. In the NYC subway case, instead of moving to a new, modern computerized system that would probably be cheaper in the long run, the Metropolitan Transit Authority has had to focus its limited budget on maintaining the frail, antediluvian network, trapping New Yorkers into an transit system light years behind, say, Japan's. (There have been stories in the recent past about the subway's upgrades, but they have mainly been superficial.)

Not all of you depend on the subway, or fly B-2 bombers, so here's a closer to home example: Windows vs. OS X. The latter is lighter, faster and springier, because it dumped all of the Classic OS's code. A fresh start, with a transition eased by the Classic emulation scheme. Windows Vista, on the other hand, is burdened by 20 years of legacy code, code that it could be argued is essentially obsolete. So we pay the price with a bloated operating system that struggles under its own massive girth. Dumping all that dead weight for Windows 7 and starting fresh—while painful—would be the best thing Microsoft could do. But it's not that easy, or they'd have done it, obviously. Maybe. You got any better examples of painful obsolescence? [IEEE Spectrum, NYT]

The B-2 Spirit follows the same ideas pioneered by John Knudsen Northrop, who founded Northrop to pursue his flying wing designs, and the Nazi Horten Ho-IX, one of the most advanced planes at its time, designed by the Horten brothers.

The Ho-IX, also called Gotha Go 229 or Ho 229, took off for the first time in 1944 and was the only plane to meet Luftwaffe's chief, frustrated transvestite and absolute nutter Hermann Göring 1000-1000-1000 performance standards: the Horten was capable of transporting 1,000 kilograms of bombs (2,200 lb) over 1,000 kilometers (620 miles) at 1,000 kilometers an hour.

Fortunately, it never reached production and most airframes were destroyed by US forces to avoid the Soviets getting their paws all over them. The U.S. VIII Corps of General Patton's Third Army captured one, however, and its low-drag, no-unnecessary surfaces live now in the B-2.

Unlike the experimental Horten and the flying wing designs that Northrop designed in the 40s (like 1948's Northrop YB-49, a jet-based variation of the 1946's YB-35 strategic bomber) the Spirit became fully operational.

The B-2 bombers are amazingly efficient: like its 20 sister vessels still in service, the Air Vehicle-12 Spirit of Kansas was capable of delivering both conventional and nuclear bombs to any target around the world in a few hours, with just one refueling. Powered by four General Electric F118-GE-100 turbofans capable of 17,300 pounds of thrust each, the aircraft can reach 410 knots (470mph) at a maximum altitude of 50,000 feet.

Another advantage of its simple design —coupled with its radar-absorbing coating, called Alternate High-Frequency Material—is that their radar profile is extremely low. Coupled with its operational altitude, this make them extremely hard to detect and shoot down. That's the reason why this crash, with no known reasons yet, is so exceptional. That and the effect of watching $1.2 billion dollars disappearing in an crater in a concrete runway.

According to the Air Force, an investigation is currently under way about why the Spirit of Kansas went to Oz at Guam. But don't worry, taxpayers, I'm sure you will get a cool 3D simulation of how it all happened from the Wizard in Chief, General Dorothy and Commander Toto, at the Pentagon.
